保護(hù)環(huán)境英語(yǔ)作文 篇1
There are many diseases that are harmful to human health and even threaten human life. Human into the 21st century, the world has occurred in the number of amazing changes. In the people for the rapid development of science and technology, but also experienced a better anxiety and even disaster. In addition to the panic of the development of high-tech, especially biotechnology, war and disease seem to bring mankind directly to the door of hell.
Water pollution on the human body harm, the body in the process of metabolism, with drinking water and food, the water of various elements through the digestive tract into the various parts of the body. When the lack of water in some of the human life process necessary elements, will affect human health. For example, in some areas of water iodine deficiency, long-term consumption of this water, it will lead to "big neck disease", is the medicine called "endemic goiter." When the water contains harmful substances, the greater harm to the human body. Carcinogenic substances can be consumed by eating contaminated food (food, vegetables, fish, etc.), into the human body, but also through the water into the human body. According to the survey, drinking contaminated water, suffering from liver cancer and gastric cancer and other cancer incidence, than drinking clean water is about 61,5% higher. When the sewage contains mercury, cadmium and other elements into rivers and lakes, the aquatic plants put mercury, cadmium and other elements to absorb and enrich them, fish eat aquatic plants, and in its body to further enrichment, people eat poisonous Fish, mercury, cadmium and other elements in the human body enrichment, so that the human body and death. In this way, from the aquatic plants → aquatic small animals → small fish → big fish → the body, forming a food chain. The body eventually became mercury, cadmium and other elements of the "foothold."
Water pollution hazards to aquatic organisms Water lives in a variety of aquatic animals and plants. Biological and water, between biological and biological complex material and energy exchange, from the number to maintain a dynamic balance. But under the influence of human activities, this balance has been destroyed. Some of the beneficial aquatic organisms are poisoned when humans release pollutants into the water, and some of the stained aquatic organisms will multiply, consume a lot of oxygen dissolved in the water, so that the beneficial aquatic life is forced to relocate due to hypoxia Or death. In particular, some toxic elements, both difficult to dissolve in water and easy accumulation in the body, causing great harm to humans. Such as mercury in the water content is very low, but the content of aquatic organisms is very high, the content in the fish is also surprisingly high. Assuming that the concentration of mercury in the water body is 1, the concentration of mercury in the aquatic organisms is about 700, and the concentration of mercury in the fish is as high as 860. Thus, when the water is contaminated, on the one hand led to biological and water, biological and biological balance between the damage, on the other hand some of the toxic substances continue to transfer and enrichment, and ultimately endanger human health and life.

Dear Jack，
Glad to receive your e-mail.
As you know, there has been an activity of “Construction of an energy-saving society” in our school recently. I think it is of vital importance because our society is faced with the increasing danger of lack of energy. Many reasonable suggestions are given during the activity.
In my opinion, there’re many things we can do. In our daily life, we shouldn’t waste any food or paper. It is also advisable to refuse to use disposable chopsticks and plastic bags. Besides, I think the government should make it a rule that used textbooks should not be thrown away when we graduate from school, because most of the books are in good condition and can be recycled.
Actually, there are quite a lot that we can easily do, for example, try to take buses or bicycles instead of driving cars, etc. Only with joint efforts can we help to construct an energy-saving society.
Yours，
Li Hua

Lowˉcarbon life is good for everyone. To help with the environment， I always walk or ride a bike to school instead of taking a car.
Besides， I will try to use things that can be recycled and I never forget to turn off the lights when I leave the classroom.
I think it’s my duty to live a lowˇcarbon life. And even the simplest activities can make a real difference to the environment. So I suggest we should reuse books as long as possible.
And we’d better not spend much money on expensive clothes.
If everyone does something for the environment， I believe the earth will be a better.
